Question

use the properties of logarithms to simplify the logarithmic expression.

log10 (9/300)

Please explain!!

Answer 1

Subtracting logs is the equivalent of dividing.
log 9 - log 300 = ??

Answer 2

I think they want you to show the two values as 9=3^2 and 300=3x10^2

so you have

log 3^2 - log(3x10^2)
=2 log 3 - (log3 + 2log10)

can you take it from here?
